Tie Down Xi2 Frost Free foundation - Manual (Page 3)

Concrete Installation
1. Check manufacturers set up manual to identify the amount of perimeter blocking required for pier
spacing and roof load. We offer 2 different Joist brackets for use based on amount of load needed.
2. Systems are installed in conjunction with complete Xi2 systems or at separate specified perimeter
support locations.
3. Using poured concrete pad locations under piers, drill two 3/8” X 3” deep holes in concrete using the
galvanized bracket as a guide. Attach bracket to concrete using 3/8” X 3-1/2” wedge anchors provided.
Place nut and washer on anchor; leave enough room for 1 to 2 threads showing on top of bolt. Using a
hammer, tap the wedge bolts into hole through bracket, leaving nut & washer flush with bracket.
Tighten wedge bolt securing bracket to concrete.
4. Build pier according to State, local, or home manufacturers guidelines.
5. Attach Joist Bracket support to floor joists approximately 6” from outside wall using 3/8” X 3” lag bolts in
pre-drilled holes in the Joist Bracket. Keep strut angle as close to 45 degrees as possible.
6. Attach compression strut to concrete bracket with 1/2” bolt provided. Do not tighten at this time.
7. Insert adjustable T-bar head in top of compression strut with nut screwed to top of the rod next to T.
Slide T end of strut up and position to rest in the bend of angle iron support. While holding in place, install a
minimum of 4 (#14 X 1” tek screws) self tapping screws into holes provided in the compression strut so the
two tubes are connected together with a minimum over lap of 4” to 6”.
8. Tighten nuts on strut to concrete bracket at this time.
9. Adjust support by tightening T-bar against the Joist Bracket support with adjustment nut.
